Everything seems to work only the Media Manager not. I have followed the installation steps in the information center but this doesn't bring me to a working environment. Anyone any experience with this and willing to help me ?

On Lotusphere 2010 I have followed this session Installation and Setup of Lotus Sametime 8.5 "From Zero to Hero" in Just Two Hours and within this session they where showing a screen from the connect client (at the end of the post).

The option "Sametime Audio/Video Conferencing" seems to be unavailable with all tries I have done so far. Is there any special step to make to make the Client aware of the running Media Manager server ?
